1. A recording device comprising:
a processor comprising hardware, the processor being configured to:
generate, based on temporal change in plural sets of image data that have been generated by an endoscope and arranged chronologically, pulse information on a subject;
associate the plural sets of image data with the pulse information to record the plural sets of image data with the pulse information into a memory; and
select, based on the pulse information, image data from the plural sets of image data that have been recorded in the memory to generate three-dimensional image data,
wherein the processor is further configured to perform correction to reduce change in shape that differs according to the pulse information and to enhance change in a color tone that differs according to the pulse information, and
wherein the processor is further configured to:
select image data in systole from the plural sets of image data that have been recorded in the memory to generate systolic three-dimensional image data, the systole being a phase in which a heart contracts and blood is being sent out from the heart;
select image data in diastole from the plural sets of image data that have been recorded in the memory to generate diastolic three-dimensional image data, the diastole being a phase in which the heart dilates and an arterial blood pressure is low according to a systemic vascular resistance; and
perform the correction to reduce change in shape between a systolic three-dimensional image and a diastolic three-dimensional image and to enhance change in color tone between the systolic three-dimensional image and the diastolic three-dimensional image.
